The pornography industry is massive on the internet and in recent years a lot more has become available for free. The choice has become plentiful, but some of the most popular, and therefore more trusted sites, can be found at YouPorn.com, Redtube.com, Xvideos.com and Xhamster.com. These sites all stream adult movies and clips for free. They make their money from the adverts around the video and so do not have to charge for allowing the visitor to watch the videos.
There are no doubt countless file sharing sites, which will allow you to download adult movies for free, however these should be approached with great caution. When downloading any file from an unknown source you may well be letting yourself in for a lot of trouble. These files can be riddled with viruses and also may not include what is claimed. It is therefore much safer and wiser to visit the sites mentioned above rather than running the risk of seriously damaging your computer.
If you do not want anyone else who may use your computer to know you have visited such sites, then it would be wise to delete your browsing history or as some browsers now offer, use the 'private browsing' option. This option means the pages you visit will not show up on your browser history.
